Ford DOES show Limited Slip available on E-Series, and it's something I would be willing to pay for as an option on a new RV. I don't think I'd pay to retrofit one.

X2.

I checked my E450's differential several years ago and it's of course not Limited Slip. :( I did not order my RV but if I had, I would have ordered it with Limited Slip.

I've had GM's equivalent of Limited Slip on my 4WD pickup (which I drive in 2WD most of the time) and really like it. For instance, it makes it possible to not have to shift into 4WD just to come up the steep driveway to hour home in wet conditions. We also have switchable traction control that locks up the rear differential on our 2002 2WD family sedan and it easily comes up our wet driveway with no problems. As far back as 1972, I even ordered a brand new 3/4 ton Dodge van - that we converted into a camper - with a lockup rear differential for added traction off paved roads.

I would really like it on our small Class C for extra insurance when driving off paved roads.
